Personally, I didn't really have a childhood dream. I was lost up until the age of 16. Then I realised if I wanted something, the only way to gain that was by working for it.
So, any dream I've had since then has pretty much become a reality. I bought a very nice superbike at 19 that my dad had taken me to see as a kid when Foggy was riding it. So that was my first taste of getting something when you earn it. Since then, none stop really.
My latest dream is leaving the UK to travel. I arrive in Bangkok 31st December... I will go around Asia for a bit then I have a flight to Australia and a working visa for a year... No idea what will happen after that.
Career wise, I have progressed purely by the want to do well. I am in a position that a lot would consider very good for my age and experience. Actually, I shouldn't be in the job flat out. I have no qualifications, but I worked hard and it's paid off. Although due to the progression I've made, I will be known as 'the kid' due to being half the age of the guys on the team lol.
On that basis, no, I have not fulfilled my childhood dreams, but filled my adult ones unlike many who get complacent and just accept what they have. Drive forward! Aim for things just out of reach. You will achieve a lot more.
